Red Hat Security Advisory 2015-2108-03 – The cpio packages provide the GNU cpio utility for creating and extracting archives, or copying files from one place to another. A heap-based buffer overflow flaw was found in cpio’s list_file() function. An attacker could provide a specially crafted archive that, when processed by cpio, would crash cpio, or potentially lead to arbitrary code execution. This update fixes the following bugs: Previously, during archive creation, cpio internals did not detect a read() system call failure. Based on the premise that the call succeeded, cpio terminated unexpectedly with a segmentation fault without processing further files. The underlying source code has been patched, and an archive is now created successfully.
